ATLANTA-Exposure to psychological stress in the form of social conflict alters gut bacteria in Syrian hamsters, according to a new study by Georgia State University.

It has long been said that humans have "gut feelings" about things, but how the gut might communicate those "feelings" to the brain was not known. It has been shown that gut microbiota, the complex community of microorganisms that live in the digestive tracts of humans and other animals, can send signals to the brain and vice versa.

In general, women regret short-term sexual encounters like one-night stands more than men do. But various factors determine whether and how much they regret them.

"The factor that clearly distinguishes women from men is the extent to which they themselves take the initiative," says Mons Bendixen, an associate professor in the Department of Psychology at the Norwegian University of Science and Technology (NTNU).

CLEVELAND, Ohio (March 7, 2018)--Anxiety is one of the most common mental health disorders, and it's more likely to affect women, especially middle-aged women. Although anxiety can be caused by many factors, a new study suggests that the amount of abdominal fat a woman has could increase her chances of developing anxiety. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

A new study using surveys and classroom noise analysis shows the success of a three-year effort by faculty in the Biology Department at San Francisco State University to get smarter about their teaching. The results run counter to conventional wisdom that scientists care more about research than they do about the students in their classrooms.

In a new study published today in the Proceedings of the National Academy of Sciences, an international team of scientists reported that they can now make people less afraid of everyday objects of phobia such as snakes and spiders, by directly manipulating the brain activity in human participants.

People with undiagnosed neurocognitive deficits are undergoing hip and knee replacements at high rates and are more likely to have poorer short-term outcomes after surgery, according to new research led by orthopedic surgeons at NYU Langone Health.

The study of patients who were screened with cognitive assessments prior to undergoing a total joint arthroplasty, or replacement, showed that those who scored worse on the tests were significantly more likely to fail to progress in rehabilitation and to require admission into the intensive care unit (ICU).

Many of the current US Federal and State dyslexia laws should be scrapped as they ignore scientific evidence and privilege some poor readers at the expense of huge numbers of others, according to a leading expert in reading disability.

Professor Julian Elliott from Durham University in the UK says valuable resources are put into expensive and time-consuming tests to diagnose children which are not only often highly questionable, but also do not point to forms of learning support that are different from what should be provided to any other poor reader.

A theoretical framework explaining the risk of rare events causing major disruptions in complex networks, such as a blackout in a power grid, has been proposed by a mathematician at Queen Mary University of London.

Rare events can abruptly dismantle a network with much more severe consequences than usual and understanding their probability is essential in reducing the chances of them happening.

CLEMSON, South Carolina - As a general rule of thumb, if there is a puzzling phenomenon occurring somewhere deep in outer space, a black hole is often the culprit behind it.
